||A default controlled breathing

||A default set of ventilator

||Injury to the lungs due
to local over-inflation caused by high distending pressure
in the intrapulmonary airways.
Flow (also Bias Flow)
||A minimum continuous flow
introduced into the patient circuit at all times.
||Bilevel Positive Airway
Pressure - A mode of operation in which the breathing
circuit from which the patient breathes spontaneously
is maintained at one pressure during exhalation and a
higher pressure during inspiration.
||For a given mass of gas
at a constant temperature, the pressure of the gas is
inversely proportional to the volume occupied by the gas.
||BR - (See Frequency
||A drug that widens the air
passages of the lungs and eases breathing by relaxing
bronchial smooth muscle.
||A device used to look into
the intrapulmonary airways; may be flexible utilizing
